The Battle of Nagashino (長篠の戦い,Nagashino no Tatakai?) was an armed conflict in 1575. The battle took place near Nagashino Castle (長篠城) on the plain of Shitaragahara (設楽原) in the Mikawa province (三河) of Japan.

Both Tokugawa Ieyasu (徳川家康) and Oda Nobunaga (織田信長) sent troops to break the siege and their combined forces defeated the Takeda attack.

Nobunaga's use of firearms to defeat Takeda's cavalry is considered as a turning point in Japanese warfare. His tactical innovation was the wooden stockades and rotating volleys of fire which led to a decisive victory at Nagashino.
